Chainlens

Chainlens, built by Web3 Labs, is a blockchain explorer and analytics platform for EVM-compatible public and private chains (Ethereum, Hyperledger Besu, Quorum, Polygon, Avalanche, BNB Chain, etc.) as well as Substrate-based chains. It combines a user-friendly block explorer with powerful REST APIs for real-time transaction monitoring, smart contract verification, token and NFT tracking (ERC-20, ERC-721, ERC-1155), and integration of on-chain data with existing analytics and reporting pipelines. The API follows the EIP-3091 block explorer route conventions and is offered both as SaaS and self-hosted.

Chainlens publishes 38 APIs on the APIs.io network, including Account-Controller API, Account-Mapping-Controller API, Account-Tokens-Controller API, and 35 more. Tagged areas include Analytics, Blockchain, Block Explorer, Cryptocurrencies, and DeFi.

Chainlens’ developer surface includes documentation, getting-started guide, signup flow, pricing, engineering blog, GitHub presence, and 10 more developer resources.
